Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure free base is a colorless oily liquid, but, like many amines , older samples assume a yellowish color due to impurities resulting from air oxidation .

The reactivity and uses of TEPA are similar to those for the related ethylene amines ethylenediamine and diethylenetriamine and triethylenetetramine. It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. [2]
Tren is a common impurity in the more common triethylenetetramine ("trien"). As a trifunctional amine, tren forms a triisocyanate when derivatized with COCl 2. TREN is known to react fast in the presence of (aromatic) aldehydes to form an imine. During this process, water is formed, making it a condensation reaction.

Ethylene dichloride is reacted with ammonia as a main method of production. This process produces various ethylene amines which can then be purified by distillation. These include ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, other higher homologues and aminoethyl piperazine.
